Unlike ordinary light, laser light has a specific wavelength and amplification of this specific wavelength results in a focused narrow beam of light that can be emitted in one direction.
These differing “wavelengths” produce different types of light, such as ultraviolet, violet, blue, green, red and infrared. These waves have varying lengths and move in all directions. LEDs (Light Emitting Diodes) are different from laser diodes and are not subject to the Federal laser product performance standard.Īn ordinary source of visible light, like the sun or a light bulb, emits a mixture of invisible and visible light like waves. One basic type of laser consists of a sealed tube, containing a pair of mirrors, and a laser medium that is excited by some form of energy to produce visible light, or invisible ultraviolet or infrared radiation. Laser stands for Light Amplification by the Stimulated Emission of Radiation. What they have in common is a laser which stores energy from a source, such as, an electrical discharge, chemical reaction or powerful optical illumination that releases the energy as light. Products that use laser energy come in many sizes, shapes and forms. Notices to the Laser Industry Information
